Makes my hair feel great

4 stars out of a maximum of 5

My hair recently has really felt damaged and just overall doesn't feel like my own. After using this, I have noticed some of my curls have been resurrected from the dead and overall my hair does feel healthier. I mostly notice the difference when my hair is styled, which sometimes feel like I'm reversing the goodness this stuff does. One thing I will note is the price, this stuff is so expensive for not much product. I don't have masses of hair (between fine-medium) and I found that I went through this very quickly. Overall, I am sure I will repurchase but may have to wait till next payday!

Good stuff

5 stars out of a maximum of 5

It’s very expensive but good. I ran out and didn’t rebut for a while but it does make a difference to the strength of my long curly hair and makes it lovely and soft. Repurchased on offer as it’s so pricey and a very small amount but you only need a couple of pumps.

Expensive but worth it

5 stars out of a maximum of 5

It’s so expensive but it does really work, it shortens my hair routine down by like 15 mins too.

It's nice and helps maintains hair health

4 stars out of a maximum of 5

It's a nice product, hair seems healthy enough after use but no drastic improvements. I tend to use it when I know I'll be using a lot of heat and styling on my curly/wavy hair to help prevent damage and maintain my hair health, seems to do the trick.

Amazing product

My hairdresser recommended this to me and it has worked wonders for my hair. It is on the pricey side.

Wow after only one use, my hair is so shiny and healthy looking. Very expensive though, so only buying it when on offer.

I’ve only ever tried the in salon versions of this treatment, keen to see a change in my hair after those initial 6 washes 😍

Bleached hair

5 stars out of a maximum of 5

Used on damaged bleached hair. Initially hair doesn’t feel as soft or moisturised as other bond repairers. Use without conditioner and after a few uses hair feels a lot stronger and healthier

Perfect hair mask

5 stars out of a maximum of 5

Only used it once so far but love this product already, can feel the difference!! It's like the best hair mask you've ever used paired with bond repair you should get from Olaplex. I loved their no8 mask but it never made as much of a difference as this has
